- Make mapped_status nullable so unmapping (X button) sets NULL instead of
deleting the row — provider statuses never disappear from the UI
- normalize_series_status now returns the raw provider status (lowercased)
when no mapping exists, so all statuses are stored in series_metadata
- Fix series_statuses query crash caused by NULL mapped_status values
- Fix metadata batch/refresh server actions crashing page on 400 errors
- StatusMappingDto.mapped_status is now string | null in the backoffice
